Subject: Regression bug in drm/i915, Wrong assumption in commit e11aa36
 breaks suspend on at least lenovo x61

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

After three days of bisect I found the bug for my problem with a broken
suspend on x61p of lenovo.

The problem is commit e11aa36. It seems to be a wrong assumption that
disabling the interrupts is enough.

I'll try to revert the commit on top of 3.18.7. (It does not clean
revert.)

Regards
   Klaus
